Safety Practices Specific to Swivels
Series 249G2 Swivels Safety Information 19
Know facility safe
procedures
Most facilities have internal procedures and rules regarding safe practices within
the facility. Be aware of these safe practices and incorporate them into your daily
operation of the system.
Have first aid available
Accidents can happen even when you are careful. Arrange your operator
schedules so that a properly trained person is always close by to render first aid.
In addition, ensure that local emergency contact information is posted clearly and
in sight of the system operator.
Be aware of
component movement
with hydraulics off
The actuator rod can also drift down when hydraulics are turned off hitting
anything in its path. This uncommanded movement is because of oil movement
between the pressure/return ports and oil blow by across the piston hub. Be aware
that this can happen and clear the area around the actuator rod when hydraulics
are turned off.
Keep bystanders
safely away
Keep bystanders at a safe distance from all equipment. Never allow bystanders to
touch specimens or equipment while the test is running.
Wear proper clothing
Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that
could get caught in equipment and result in an injury. Remove loose clothing or
jewelry and restrain long hair.
Check bolt ratings and
torques
To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTS-
manufactured systems are torqued to specific requirements. If a fastener is
loosened or the configuration of a component within the system is modified, refer
to information in this product manual to determine the correct fastener, fastener
rating, and torque. Overtorquing or undertorquing a fastener can create a
hazardous situation due to the high forces and pressures present in MTS test
systems.
On rare occasions, a fastener can fail even when it is correctly installed. Failure
usually occurs during torquing, but it can occur several days later. Failure of a
fastener can result in a high velocity projectile. Therefore, it is a good practice to
avoid stationing personnel in line with or below assemblies that contain large or
long fasteners.
Practice good
housekeeping
Keep the floors in the work area clean. Hydraulic fluid that is spilled on any type
of floor can result in a dangerous, slippery surface. Do not leave tools, fixtures,
or other items not specific to the test, lying about on the floor, system, or decking.
Do not disable safety
devices
Your system may have active or passive safety devices installed to prevent
system operation if the device indicates an unsafe condition. Do not disable such
devices as it may result in unexpected system motion.
Provide adequate
lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment
damage, and personal injury. You need to see what you are doing.
Provide means to
access out-of-reach
components
Make sure you can access system components that might be out of reach while
standing on the floor. For example, ladders or scaffolding might be required to
reach load cell connectors on tall load units.
